Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Pot-au-feu, Au Bain-marie
Ingredients
Directions
Prepare
In an earthen pot, combine beef, veal, mutton, roasted fowl, and cold water.
Add carrots, turnip, leeks, celery bundle, and onion.
Cover the pot tightly with a paste made of flour and water to seal in steam.
Cook and strain
Place the pot in a larger stewpan filled with water and bring to a boil.
Maintain a steady boil for 6 hours, adding boiling water to the stewpan as needed.
After 6 hours, remove the paste and strain the broth through a silk sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavour and gelatin into the broth during long, slow simmering.
- Veal fillet
- Adds tender meat and body to the broth as it cooks slowly.
- Mutton
- Contributes rich meaty flavour and fat that enriches the broth.
- Roasted fowl
- Adds roasted, savoury flavour and collagen-rich body to the broth.
- Leeks
- Contribute mild sweetness and aromatic depth to the broth.
- Carrots
- Add natural sweetness and colour to the broth.
The step that matters
Maintaining a steady boil for 6 hours. A gentle, steady simmer keeps the broth clear and lets collagen and connective tissue break down slowly. A hard, rapid boil would emulsify fat into the liquid and cloud the broth, while letting it drop too low stalls extraction of flavour.
